ULYSSES G. MCQUEEN, OF NEW ROCHELLE, NEW YORK.

SASI-I-PULLEY.

Application filed October 15, 1913.

To all whom it may concern Be it known that I, ULYSSES G. MCQUEEN, a citizen of the United States, residing in the city of New Rochelle, in the State of New York, have invented certain new and useful Improvements in Sash-Pulleys, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to sash pulleys and is concerned particularly with the devicesfor securing the same removably' in position in the stile.

It has for its object to provide such securing devices which shall be simple in construction, inexpensive to manufacture and convenient in use to facilitate the insertion or removal of the sash pulley as required.

A further object is to provide in combination with removable sash pulleys interchangeable face plates of any desired char acter or appearance whereby the exposed surface of the pulley may be given the appearance of brass, iron or any other metal to suit the requirements of the architect. In accordance with the invention these face plates are stamped from a single piece of metal and with ears to permit their attach ment to the frame of the pulley. In this way, not only is the initial expense of such interchangeable face plates minimized, but

their capacity for ready attachment topul-.

ley frames commends them to a wide and general use.

The invention will be described more particularly with reference to the accompanying drawings in which Figure 1 is a view in front elevation of a face plate constructed in accordance with the invention. Fig. 2 is a fragmentary view partly in vertical section and partly in elevation showing the improved sash pulley secured within a. stile and indicating in dotted lines the position of the locking bolt when the pulley is removed. Fig. 8 is a rear view in elevation of the improved pulley. Fig. 4: is a front view in elevation of the improved pulley. Fig. 5 is a view in vertical section take on the plane indicated by the line 55 of Fig. 3 and looking in the direction of the'arrows.

Serial No. 795,250.

The housing a and frame 5 of the pulley c are substantially of a character well known except in so far as indicated hereinafter, and are formed with projecting portions a and b respectively, designed to engage with the stile d. in previous constructions it has been usual to fasten such interlocking frames in position within the stile by screws which enter the stile. In accordance with the present invention, however, it is desired to provide securing means which, cooperating with the interlocking frame of the pulley, shall permit an unskilled person to secure the pulley within the stile or detach it therefrom readily and without the use of special tools, other than simple ones, such as, for instance, a screw driver. These means in the present embodiment are illustrated as a headed screw 6 passing loosely through an aperture 6 formed in the lower part of the frame 6 and preferably countersunk so as to permit the head of the screw to enter thereinto to an extent suiiicient to place its outer edge in rear of the front face of the frame, for a purpose which will later appear. Then too, the aperture is of such a size as to permit the screw 6 to have a free lateral or swivel movement therein, so that it maybe swung upward with the housing a as the frame 6 is passed inward to its position within the stile. The screw has threaded on itsend a suitable nut f which, when the pulley is in position, engages the inner face of the stile cl and cooperates with the frame I) on the opposite side of the stile to lock the pulley is position, the frame in this instance resting in a rabbeted portion at of the stile.

It will now be evident that when the pulley is to be secured within the stile, the headed screw 6 being in the position indicated in dotted lines in Fig. 2, the projecting portions at and b of the housing a and frame 6 respectively are placed in interlocking engagement with the stile d as the pulley frame is swung inward. During this inward move ment the lower edge of the nut), which may be beveled, as at f, slides along the exposed edge of the stile 03 until the pulley frame a is substantially in its proper position when the nut f will ride off of the exposed edge of the stile and assume some such general position as indicated in full lines in Fig. 2. The threaded screw 6 may then be set up until the head thereof is in binding engagement with the frame 7) and the nut f is in corresponding engagement with the inner face of the stile cl. It will be understood that the operation outlined above will be merely reversed for a ready removal of the pulley from its position. The use of such a screw 0 as has been described might be open to the objection thatbecause of its latitude of play within the aperture it could not readily be placed in its desired position with respect to the stile as the frame is moved into position. This objection is met in the present invention by forming the housing a with depending flanges at? extending clownwardly to a point substantially opposite the normal locking position ofthe screw and serving as guides therefor in its movement in substantially a vertical plane. These flanges a may be curved inwardly 'ad]acent their lower edges so as to facilitate this guiding action with respect to the screw 6. It will now be seen that when the pulley is to be mounted in position, the screw e with its nut f can'be pressed upwardly between the flanges 64 and the lower end of the housing then moved inwardly, as described, and the mechanic need have no concern for the final resting position of the screw since it is guided positively. Moreover the flanges a hold the nut from turning when the screw is being set up.

It is to be noted that the inside lower edge of the front opening of the frame I) is beveled inwardly, as at Z2 and that its upper inside edge is correspondingly beveled as indicated in dotted lines in Fig. 2. These beveled edges are provided to cooperate with corresponding ears 9 struck up from an integral face plate g which has the same out line as the front face of the frame I). The face plate 9 may be stamped from asingle piece of material and, as will be-understood, this material may be of any desired character although usually it will be of metal, such as brass, iron, etc. In the lower portion of the face plate 9 is stamped an aperture g which registers with the aperture 6 in the lower portion of the frame Z2 when the face plate issecured in its normal position on the frame. In attaching this plate 9 to the frame Z) the ears 9, which may lie sub-. stantially at right angles to the face of the plate or be inclined thereto, as indicated in Fig. 2, are passed inwardly through the front opening of the frame 6. In case the ears are substantially at right angles to the plate, it will be desirable to press them downwardly on to the beveled edges 6 and,

b of the frame Z). If the ears 9 are inclined to the face plate 9, as in the present embodiment, it may be necessary to bow the face plate slightly as the ears are passed inwardly to their positions in engagement with the beveled edges Z2 of the frame.

It will now be appreciated that whereas it has generally been necessary for merchants to keep in stock a great number of sash pulleys provided with exposed faces of as many different metals as the purchasers might require, it now becomes possible for the merchant to keep in stock a relatively small number of pulleys and a number of face plates, such as g, of dissimilar metals.

The latter being, of course, relatively inexpensive as compared to the pulleys themselves, the risk of the merchant" through overstocking is eliminated while all possible requirements of purchasers may be satisfied.

It will also be seen that'the pulley can be sold with the screw in place and prevented by the nut from falling out, so that the, user is spared the necessity of looking for a screw when he is ready to put the pulley in place.

Modifications of the embodiment of the invention herein illustrated may be made by skilled mechanics and all such modifications are to be deemed within the spirit of this invention.

I claim as my invention:

1. In combination, a sash pulley adapted to interlock with the stile, a headed screw mounted to swivel in the frame of the pulley, and a nut carried on the threaded end of the screw and adapted to engage the stile, the headed screw and the nut serving to hold the pulley removably in the stile.
